Title: Light deflecting device
Inventor: WANAMI HIDEKI
IPC: G02B26/12
Filed: 1986-07-31
Abstract: PURPOSE:To speed up restoration from disturbance by providing a face inclination variable detecting means for respective reflecting surfaces of the polygon mirror, a means for storing respective face inclination variables in each reflecting surface and a means for correcting the face inclination variable read out from the storing means in a light deflecting device for deflecting light projected from a light source by a rotary polygon mirror. CONSTITUTION:A face inclination variable detector 5 consisting of a CCD line sensor is driven by clock pulses generated from a clock generator 21 connected to a counter 22 and an obtained detection signal is compared with a reference level VS1 by a comparator 23. The compared signal is applied to a storage device consisting of memories 31-35 connected in series through a latch circuit 24 and a contact (a) of a change-over switch 30 and the final memory 35 is connected to a contact (b) of the switch 30 and also connected to a D/A converter 25 through a switch 36. The output of the converter 25 is applied to a correcting mechanism driving device 11 through a comparator 26 having a reference level VS2 and an amplifier 27. If it is unnecessary to store data, a storage circuit is removed by using the switch 30.

Title: Optical amplifier
Inventor: TAMURA YASUAKI
IPC: H01S3/06
Filed: 1991-07-22
Abstract: PURPOSE:To prevent self-oscillation of an optical amplifier without attenuation of the pumping light. CONSTITUTION:A pumping light generated by a pumping laser 5 is inputted to an Er doped fiber 9 through a short wavelength pass filter 7 and a multiplexing filter 4 for blocking the light of a signal light wavelength band. Since a part of a spontaneously emitted light generated in the Er doped fiber 9 is blocked by the short wavelength pass filter 7 though the part of the light passes through the multiplexing filter 4 and advances toward the laser 5, the light is not returned to the Er doped fiber 9 by reflection by the laser 5, thus, self-oscillation can be prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable transmission line by shortening or eliminating hit time when a communication path is switched (time when it is relieved in opposite rotation), which is the defect of a former double ring-like transmission line. SOLUTION: A device (opposite device) becoming a communication opposite party connected to the same L ring and the R ring as this communication equipment is assumed.
